ELECTRIC SNAP j i Application filed December 23, l1%.?1191..

To @ZZ iv/tomrz't may concern.'

'Be it known/that'l, CHARLEs SPRIC, a citizen' of' the `United States, residing at Rutherford, inthe county of" Bergen, State New Jersey,have invented certan'new Q Land useful Improvements kin Electric Snap is seated;

switch comprisingfa `receptacle of porcelain' or yother insulating material forming a protective".covering-'for the `mechanism of the y lswitch', a formedimetal yoke to-which thev Switches, of rwhich the iiollowing is a full,

clear, conciseandjexact description.

This-invention relates' to electric .switches and'\morfe rparticularly to snap switches. Specifically it is" a s'napfswitch.`

-lt 4is the objectief,thsinvention` to provide a lever operated snap switch of simpleand inexpensive construction which is' durable,

- eilicient in .opera-tion, 4and easily and quick- `lylassembled'.'`

In Fig.,k l, operating lever 9kis shown ink In "operation,v rocker me ber 6 quickly.'

direction of the force exerted onthe rocker arm through the medium of spring 13 has been shifted to the opposite side of ulcrum pin 10` from that in which it is indicated'in Fig. 1. The tendency thens for the rocker `membeiryand contact brushes' to be moved from the positionl in which they are' shown in` Figs.- k1 and 2, and when. the operating lever is moved rarenough to put suicient tension on spring'l, that movement :will

occur andthe contact brushes will be quickly shifted to the position shown inFig. 3. The reverse ofthe 'aboveaction will occur when the operating'lever is moved inthe opposite' direction f Y I -The "facility with which the operating mechanism" of .this switchy is assembled is best described with reference tol Fig-6. 0perating lever 'v9 ispli'rst put position, its lrule-ruin pin 10 seating inslo't 1 1 of collar 5.

It isr then easily Jforced into its proper position. n s' the ,methodoj assem@ bling the otherparts is obvious romjthe il-` lus'trations, it will require no further de sfcription l y What is'claimed is:

1. Ina snap switch, an operating lever, a rocker member comprising a U-shap'ed metal .stamping with a laterally projecting hookv aty its middleportion, a? yoke to which saidy operating lever and s-aid rockermember arepivotally attached, a spring attached fat one"endtosaid` operating lever land at the ether'v endto'thehook of saidf rocker member,

"atmov-a'blecontact member attached to; said rocker member, and a stationary: contact member cooperating withk said Trnovabley conf tact member".1 i

2.V lnfa snap switch, ayokegcomprising a bridge and two inwardly projecting arms integral with said bridge, van outwardly pro- .jecting threaded collaron said yoke and having a slot acrossy itscenter portion, a face plate with an aperture through which said vcollar projects, a nut engaging said coll-ar saidrockerfmember whereby said vrocker v memberis .operable by the movementof said operating lever, a contact member attached to and movable with said rocker member, and aA stationary contact cooperat- ,ingv with said movable `contact member. i

3.' In a'snap switch, a yokecomprising a bridge and two inwardly projecting arms in- '-tegral with said bridge, a collar on said yoke, a faceplate with an aperture through which said col].ar"pro]ects, a nut engaging saidcollar on said'tace plate, an operating lever pivoted in said collar comprising an oiitwardly projecting arm and an inwardly projecting arm and a hook Vat the .endpor# U-shaped metal vrocker memberV with a' lat- JQ tion;y a spring pivotally-attached at one end to the .hook oi"- said operating lever andat the other end to the hook o saidv rocker member whereby said rocker member isoperable'bythe movement of said operatingr lever', contact inember'attached to and movable withy said rockerrnember, and a tion oithe inwardly vprojecting arm, 'a

f erally` nrojectinghook 'at its middle-porstationary contact cooperating with said' movablecontact'member. l
